Transition metal complexes of a tetradentat macrocyclic ligand 1,3,10,12-tetraazo-4,9,13,18-tetraoxo-2,11- dithiacyclo octadecane and bipyridine

Abstract

The research involve the preparation of some transition metal complexes of Mn (II),Fe(II),Co(II), Ni(II),Cu(II) and Zn(II) with tetradentate ligand 1,3,10,12-tetraazo-4,9,13,18-tetraoxo-2,11-dithiacyclo octadecane (L) and some adducts with some doner ligand such as bipyridine (bip) as a bidentate ligand .These complexes and adducts were characterized by means of micro analysis (M),molar conductance measurements, magnetic measurements Infrared and electronic spectral techniques.
